New strategies in haemodiafiltration (HDF): prospective comparative analysis between on-line mixed HDF and mid-dilution HDF [PDF]

open access: yesNephrology Dialysis Transplantation, 2007
Improvement in the uraemic toxicity profile obtained with the application of convective and mixed dialysis techniques has stimulated the development of more efficient strategies. Our study was a prospective randomized evaluation of the clinical and technical characteristics of two new haemodiafiltration (HDF) strategies, mixed HDF and mid-dilution HDF,

NICMOS observations of the HDF [PDF]

open access: yesThe 9th astrophysics conference: After the dark ages, when galaxies were young (the Universe at 2<Z<5), 1999
This paper presents initial results and performance levels from the Near Infrared Camera and Multi-Object Spectrometer (NICMOS) observations of the Hubble Deep Field (HDF). These observations represent the deepest view of individual objects yet obtained with photometric colors of some objects indicating redshift values greater than 6.

Impact of Limpware on HDFS: A Probabilistic Estimation

open access: yesCoRR, 2013
With the advent of cloud computing, thousands of machines are connected and managed collectively. This era is confronted with a new challenge: performance variability, primarily caused by large-scale management issues such as hardware failures, software bugs, and configuration mistakes. In our previous work we highlighted one overlooked cause: limpware

HDF: Introduction and Motivation

open access: yes, 1997
Although it is just over a year since the data was made public, the HDF exposure has stimulated considerable progress towards our understanding of the faint galaxy population. I present a brief personal account of the history of faint galaxy studies culminating in the HDF, and describe what I consider to be the main highlights thus far from this ...
